Re: [Pharo-project] Multiple worlds // how to switch between them...

by H. Hirzel

To be more precise. Is there another way than WorldManager instance createOrSwitchToWorldNamed: 'myOtherDesktop'. and then back with WorldManager instance createOrSwitchToWorldNamed: 'Pharo'.

Hello again, A follow-up question. I loaded the TilingWindowManager (TWM) by Laurent Laffont. ( MetacelloConfigurationBrowser open. ) TWM is supposed to support multiple virtual desktops. How do I start using this feature? E.g. a pointer to a blog entry? Thank you in advance. --Hannes On 8/28/12, H.

> Cannot parse. You want to integrate it till it fails? :) Yes.. keep it in from now on in the main base till it shows up as unusable. I do not mind occasional instability.. or something I can workaround... :). Need to learn and deep dive to use it to exploit its potential ... which is huge.. at the minimum as a replacement to FFI.. I guess more efficiently.. **** Rest is all fine.. its a great piece of work.. will dive into ARM / et als when I do need them over the next year..

Hello Any news on having multiple virtual desktops in Pharo? I currently use Pharo 1.4, maybe it is in 2.0?

Re: [Pharo-project] Again: Basic Questions about NativeBoost

Hi, In Pharo 2.0 (perhaps not the latest one), NBFFICallbackTests -> 10 run, 7 passes, 3 expected failures so I would say that NB supports some callbacks ;-) Cheers, #Luc 2012/8/28 drush66 <davorin.rusevljan(a)gmail.com> > Does NB support writing callbacks in smalltalk that can be called by > external > library? > > > > ----- > http://www.cloud208.com/ > -- > View this message in context: > http://forum.world.st/Again-Basic-Questions-about-NativeBoost-tp4645447p464… > Sent from the Pharo Smalltalk mailing list archive at Nabble.com. > >

You want to sanely encode to in-memory bytearrays, use the Zn converters. You want to conveniently switch between putting binary and encoded contents to a filestream (and do so efficiently), use the TextConverters. Cheers, Henry

[Pharo-project] Who broke UTF8TextConverter?

by Igor Stasenko

or it was like that from the birth?? arrrrgghhhh... | stream | stream := WriteStream on: (ByteArray new: 100). UTF8TextConverter new nextPut: (Character value: 129 ) toStream: stream. stream contents #[129] This is WRONG! RTFM, about utf8 encoding, please! :) --------- nextPut: aCharacter toStream: aStream | leadingChar nBytes mask shift ucs2code | aStream isBinary ifTrue: [^aCharacter storeBinaryOn: aStream]. in my case, stream is binary, so it goes directly to #storeBinaryOn: storeBinaryOn: aStream "Store the receiver on a binary (file) stream" value < 256 ifTrue:[aStream basicNextPut: value] ifFalse:[aStream nextInt32Put: value]. This is not even close to UTF8. If character code is less than 256, it will store a single byte (wtf?), and if more than that, it will store 32-bit integer value in big-endian order (wtf raisedToPower: 2).. i wonder , for what purpose we actually having this code path? this stuff is completely useless. according to implementation of storeBinaryOn: there's no way how you can read the same character value back. because it can be 1 byte or 4 bytes.. but you simply cannot determine which one. this is one of the reasons we using utf8 encoding, btw ;) -- Best regards, Igor Stasenko.
